Heater Assemblies, Gas Turbine Engine Systems Involving Such Heater Assemblies and Methods for Manufacturing Such Heater Assemblies

摘要

Heater assemblies, gas turbine engine systems involving such heater assemblies and methods for manufacturing such heater assemblies are provided. In this regard, a representative method includes: providing a substrate; forming a heating element using a thermal sprayed metal process such that the metal heater comprises an aggregation of sprayed metal particles; attaching the heating element to the substrate; and consolidating at least some of the metal particles located at an exterior of the heating element to form an electrical contact pad of the heating element.
